The success of the Duke and Duchess of Cambridge's recent tour of Canada and California was due, in part, to how good the couple looked. After years in the fashion wilderness Prince William, who's finally discovered his sartorial mojo, is following in the footsteps of his well-dressed forebears.

The current strand of British royal style goes back to the middle of the 19th century when, in the 1860s, King Edward VII, the then Prince of Wales, invented what has come to be known as the tuxedo. His son, George V, also had a strong sense of style, and his grandson, the Duke of Windsor, was one of the best-dressed men of the past century.

While none of the current Windsor men enjoy The Duke of Windsor's status as a fashion plate, the best dressed of them display notably contrasting styles. Here we review the wardrobes of the Queen's husband (the Duke of Edinburgh), the Prince of Wales, the Queen's first cousin (Prince Michael of Kent), and the Duke of Cambridge. In particular pay attention to the manner in which each man knots his tie, a strong clue, it's been said, to the state of a man's mind.
